For a very short game I like how the voice and sound has been implemented very well. Little humor's here is a great touch that makes the mood swing which adds to tension that really pushes you slightly of guard. There are moments where I have been on the edge of my seat. The map looping in the same locations also adds so much to mindgames. There are some sign postings that are really helpful as well. And the rest is just memorizing the layout on and on.
The end sequence was very short though, I was hoping to get chased by the angel more often but it is very easy to avoid him and finish the game.

A thing that annoyed me was the flashlight doesn't really point where I am looking but rather downward. Also not knowing which locker the phone is in is just frustrating, there can be a better way to find Joey's locker perhaps.

I think with all the neat little tricks and details above adds to the quality of the game so much, and I enjoyed it more than I was expecting from a horror game.
